Right to a fair trial
The right to fair trial is an essential right in all countries respecting the rule of law. A trial in these countries that is deemed unfair will typically be restarted, or its verdict voided.
Various rights associated with a fair trial are explicitly proclaimed in Article 10 of the Universal Declaration of Human Rights, the Sixth Amendment to the United States Constitution, and Article 6 of the European Convention of Human Rights, as well as numerous other constitutions and declarations throughout the world. There is no binding international law that defines what is or is not a fair trial; for example, the right to a jury trial and other important procedures vary from nation to nation.
